Question

The given diagrain shows a stage during mitotic division in an animal cell.
(o Identify the stage. Give a reason to support your answer.
(1) Draw a neat labelled diagram of the cell as it would appear in the
next stage. Name the stage.
(s) In what two ways is mitotic division in an animal cell different
from the mitotic division in a plant cell?
(iv) Name the type of cell division that cor's during
(a) growth of a shoot.
(b) formation of polien grains.

Answer 1

Explanation:

1. The stage shown in the diagram is of late prophase as the condensed chromosomes are formed from chromatin and spindle fiber formation also have started for following metaphase.
2. it would be metaphase (image has been provided)
3. Mitosis

• in plant cell, Centrosome and centrioles absent. Cell plate developing from the center and growing towards periphery during cytokinesis.
• Mitosis in animal cell, Centrosome and centrioles are present, Cell furrow develops from periphery grows towards center during cytokinesis.

a)  growth of shoot: mitosis

b)  formation of pollen grains (as they are gametes): meiosis
